Library usage

Warning: not finished.

Working example of gate-reduction and code parsing:

def do(x):
		e = x * 5
		b = e * 6
		c = b * 7
		f = c * 1
		d = c * f
		out = d * mul(d,e)
	
	def doSomethingElse(x ,k):
		z = k * x
		out = do(x) + mul(x,z)
	
	def main(x,z):
		out = do(z) + doSomethingElse(x,x)
	
	def mul(a,b):
		out = a * b
